Miniature golf, also known as minigolf or crazy golf, is an offshoot of the sport of golf focusing solely on the
putting aspect of its parent game. It is played on courses consisting of a series of holes (usually a multiple of 9) similar to its parent, but characterized by their short length (usually within 10 yards from tee to cup), the use of artificial putting surfaces such as carpet, astroturf and/or concrete, a geometric layout often requiring non-traditional putting lines such as bank shots, and artificial obstacles such as tunnels/tubes, ramps, concrete/metal/fiberglass forms, and moving obstacles such as windmills.
While the international sports organization World Minigolf Sport Federation (WMF) prefers to use the name "minigolf", the general public in different countries has also many other names for the game: miniature golf, mini-golf, midget golf, goofy golf, shorties, extreme golf, crazy golf, adventure golf, mini-putt and so on. The name Putt-Putt is the trademark of an American company that builds and franchises miniature golf courses in addition to other family-oriented entertainment, and the term "putt-putt" is sometimes used colloquially to refer to the game itself. The term "Minigolf" was formerly a registered trademark of a Swedish company that built its own patented type of minigolf courses. Resort towns such as Myrtle Beach, SC, Branson, MO, Pigeon Forge, TN and Wisconsin Dells, WI are known for their numerous minigolf courses.
